This is the site where the famous Japanese USUKAN WW2 Wrecks previously lay; Merchant Tankers Kolusei Maru, Hiyori Maru and Higane Maru. The ships were sunk by deadly torpedoes fired by American Submarine USS Hammerhead back in 1944. Sadly, they were very recently salvaged for valuable steel and a pile of scrap metal on the sea bed is now all that remains of the ships. Nonetheless, this is still a great site to explore for the artificial reef that has thrived around the structures and the huge schools of fish which shelter here. Watch out for predatory tuna and jacks hunting in the blue. Schools of barracuda and snapper blanket the top of the wreck and a chance to encounter large pelagic fish makes this a spectacular site. Keep a look out for eagle rays, huge marble rays and giant groupers that live under the remains of the wreck. Bare in mind that over 128 passengers and crew lost their lives here. Viewing the ghostly wreck remains in the dark blue deep makes for an especially eerie dive.
